The fixed sources, as well as executeables for both the original and fixed versions, are available from Pete Galvin's archive. Do an anonymous FTP to r20.utexas.edu, cd to , and get nansis.asm. The executeables are there too, if you want them. Beware, however, that r20 is a tenex/twenex machine, and may mangle binaries when transferring them to non-tenex/twenex systems. Get around this by setting tenex mode on in FTP, if you need to. Hopefully helpfully, Brent -- Brent Chapman chapman@pavepaws.berkeley.edu ucbvax!pavepaws!chapman TANSTAAFL!
